​To save this beautiful brindle boy, it would require folks to rally around Riley. A one-year-old Labrador Retriever-Plott Hound mix, Riley arrived at the Duplin County Animal Shelter in North Carolina on December 10th. We don't know how or why Riley ended up in the shelter, but we do know that testing heartworm positive at this rural overcrowded high-kill shelter put his life at risk.
